Been through Ryse one and a half times... Might get through it twice, but probably not a third time...
 
Red Dead Redemption
Half Life 2
Max Payne 3
Uncharted 2
Skyrim

That's just the games from last gen. There's dozens more if I were to include games from the 8-bit era until now.
 
Back in the PS1/PS2 days (when i was very young) every game pretty much I'd go through multiple times.

The last few games that i played through multiple times were MGS4 and GTA 4/5
 
In recent times:

  • All the bethsoft games: Morrowind, Oblivion, Fallout 3, Skyrim and all DLC
  • Diablo III (you kind of have to keep redoing the campaign, I'm probably at about 40 times now across different chars / difficulties)
  • Demon's Souls (4-5 times now)
  • Dark Souls (3 times)
  • Torchlight (lost count)
Probably a few more in recent years, but those are the big ones. Without these, I probably would have just quit gaming. They are what keeps me doing it, specially diablo-style games and Bethesda open-world RPGs.
